God, in Christ, not only redeems each of us individually, but he also redeems social relations between individuals. The Church community, gathered together in Jesus Christ and in the power of the Holy Spirit, is the catalyst for the transformation of social relationships.
This social transformation is a task entrusted to the Christian community which is to develop it and practice it through continual reflection on the Gospel. This reflection is necessary, for the redemption of society in Christ is not a static, once and for all time event. Christians seek dialogue with all people of good will in the common quest for truth and human freedom. This dynamic dialogue must be firmly rooted in the unchangeable principles of natural law, inscribed by God in the heart of all.
The fundamental law of human and social perfection is the law of love. It is the ultimate measure and rule of every human relations. It is the mystery of God himself. The law of love is our authentic purpose both historical and transcendent. Therefore, “earthly progress must be carefully distinguished from the growth of Christ’s kingdom. Nevertheless, to the extent that the former can contribute to the better ordering of human society, it is of vital concern to the kingdom of God.” Gaudium et Spes, 39.
